【摘要】：研究目的:HIIT作為熱門健身方式,其減脂效果受到國內(nèi)外科研者廣泛關(guān)注。本研究通過8周HIIT、MCT,選用無運動訓(xùn)練經(jīng)歷的健康男性,旨在比較兩組的體成分、靜息代謝率及運動后過量氧耗階段脂供能相關(guān)指標(biāo)的變化特征,進而分析訓(xùn)練前后產(chǎn)生差異的脂供能因素,探討HIIT減肥方法對健康男性青年的應(yīng)用效果與可靠性,為大眾運動健身減脂開拓新的思路。研究方法:本研究將18名健康青年男性隨機分為H組、M組各9名。訓(xùn)練采用跑臺,每周3次,一次30分鐘,共8周,且在中期對強度進行校正。H組采用90%V02max強度,運動3分鐘、間歇2分鐘,共6組;M組采用60%V02max強度,運動30分鐘。對各組受試者的安靜狀態(tài)、運動之前、運動過程中和運動結(jié)束恢復(fù)期這四個階段進氣體和生化代謝的測量。主要監(jiān)測項目有體成分、RMR、TG、FFA、血清甘油、EPOC總量及持續(xù)時間。所有數(shù)據(jù)采用SPSS18.0軟件進行處理,數(shù)據(jù)采用MEAN土SD表達。對組內(nèi)和組間干預(yù)前后的指標(biāo)統(tǒng)計方法分別為配對樣本T檢驗、獨立樣本T檢驗。其中,訓(xùn)練期間的血液指標(biāo)采用重復(fù)測量方差分析。當(dāng)P0.05時為顯著性統(tǒng)計學(xué)差異。研究結(jié)果:1干預(yù)后,僅H組體脂率(%)、腹部脂肪質(zhì)量(kg)顯著性下降。2干預(yù)后,H組RMR(kcal/kg·d)顯著性提升。3 H組EPOC持續(xù)時間及總量、脂肪氧化量、總能耗、脂肪供能比例均顯著性大于M組。4干預(yù)后,H組過量氧耗期間RER、FFA變化幅度顯著性大于M組,提示,HIIT有利于運動后恢復(fù)期脂肪動員的加強。研究結(jié)論:1 HIIT和MCT都能起到降低體脂率、減少腹部脂肪質(zhì)量、提升靜息代謝率的作用。2 HIIT對健康青年男性產(chǎn)生的EPOC總量、持續(xù)時長顯著性大于MCT。3相比MCT,8周的HIIT尤其對快恢復(fù)期(AS0-10)脂肪氧化量、慢恢復(fù)期(AS10-30)總能量消耗影響較大。4 EPOC與FFA代謝密切相關(guān),相比MCT,HIIT更利于此階段的脂肪動員、脂肪供能。
[Abstract]:Objective: as a popular fitness method, the effect of reducing fat on HIIT was widely concerned by researchers both at home and abroad. The purpose of this study was to compare the body composition of the two groups by 8 weeks HIITT MCTT and healthy male without exercise training experience. The characteristics of metabolic rate of rest and the related indexes of lipid supply during the period of excessive oxygen consumption after exercise were analyzed. The factors of lipid supply before and after training were analyzed, and the effect and reliability of HIIT weight-loss method on healthy young men were discussed. In this study, 18 healthy young men were randomly divided into H group (n = 9) and M group (n = 9). In the middle period, the intensity of group H was corrected with 90 V 02max intensity, 3 minutes of exercise and 2 minutes of interval. Group M was treated with 60 V 02max intensity and 30 minutes of exercise. Measurement of gas and biochemical metabolism in the four stages during exercise and during the recovery period after exercise. The main monitoring items were RMR-TG-FFA.The total amount and duration of serum glycerol were measured. All the data were processed by SPSS18.0 software. The data were expressed by MEAN soil SD. The index statistical methods before and after intergroup intervention were matched sample T test and independent sample T test respectively. The blood indexes during training were measured repeatedly by ANOVA. There was significant statistical difference when P05 was used. After intervention, the RMR(kcal/kg 路d of group H significantly increased the duration and total amount of EPOC, the amount of oxidation of fat, and the total energy consumption. The ratio of fat to energy supply was significantly higher than that of group M during the period of excessive oxygen consumption after intervention, suggesting that it was beneficial to the enhancement of fat mobilization in the recovery period after exercise. Conclusion both HIIT and MCT can decrease the rate of body fat in group M, and the ratio of FFA in group H is significantly higher than that in group M during the period of excessive oxygen consumption. The effects of decreasing abdominal fat quality and increasing resting metabolic rate on the total amount of EPOC produced by 2. 2 HIIT in healthy young men were significantly longer than that of HIIT in 8 weeks of MCT.3, especially in the fast recovery period. The total energy consumption of AS10-30) was closely related to the metabolism of FFA, which was more favorable for fat mobilization and fat energy supply than MCT-HIIT.
